Each A/D module provides field programmable input range and gain for each channel. The ability to set lower than expected, full-scale voltage gain ranges assures the use of the full resolution. Each channel includes an anti-aliasing filter with an inherent digital ‘brick wall’ filter and a digital second-order IIR low-pass filter with a programmable breakpoint that enables users to field-adjust the filtering for each channel.
All channels have continuous background Built-In-Test (BIT). The modules also include extended A/D FIFO buffering capabilities for greater storage/management of the incoming signal samples (data) for post processing applications. Programmable FIFO buffer thresholds maximise data flow control (in and out of the FIFO). Incremental relative time-stamping between samples is also provided as a programmable option.
“The A/D function modules are part of a group of over 40 unique function modules,” stated Lino Massafra, VP of Sales and Marketing. “Our modules can be used with any of our latest generation multifunction I/O and SBC cards and in our Sensor Interface Unit systems to offer our customers the widest array and highest density of I/O in the industry.”
